Agent Skills: building-writing-kits

Build a writing kit, everything a person needs to write a doc themselves (sourced facts, verbatim quotes, the choices a draft made, reader objections, open questions, blanks only they can fill) without the finished prose. Use whenever the user wants material or "inspo" to write a brief, memo, RFC, PR/FAQ, proposal, review, or post in their own words, says they will write it themselves, asks for research or a packet to write from, wants an existing draft taken apart into what went into it, or wants their finished doc checked against the sources.
